I know there is a section for attire but this problem doesn't necessarily fit there in my opinion so I'm posting here.
That being said, here is my dilemma:
My sister is in my wedding party. This past Sunday, her husband and I were talking and he mentioned that he was planning on buying an authentic Scottish kilt this summer. He then proceeded to tell me that he will undoubtedly be wearing this new kilt to my fiance and my Spring 2012 wedding. Now, I know the wedding is almost a year away and he very well could change his mind, but this has been on my mind since it came up. I know I can't control what he wears, but is it being a bridezilla if I prefer him not to wear the kilt for the family pictures? Honestly, if he wants to wear it for the reception, that's one thing. I just really don't want to look back at our pictures and have him be wearing a blue/green plaid kilt while the rest of the family is in black tie attire.
I know this sounds really bridezilla-esque and completely understand if it is not appropriate to ask him - just looking for a little advice.
Thank you all in advance
